Wayne Rooney and Manchester United are invariably tied together when you look at how things have panned out for the Red Devils over the last nine years, but the 27-year-old's future at Old Trafford is very much in doubt right now.

David Moyes is taking over for Sir Alex Ferguson as the club's manager, but it's unclear whether Rooney will be joining him to help United defend their English Premier League title in the upcoming season.

Ferguson crashed headlines in May when he claimed Rooney asked for—and was denied—a transfer toward the end of the EPL season. Chronicled here in a report from Jamie Jackson of the Guardian, Ferguson then placed the decision on Rooney in the hands of the new manager.

Looking back, it was that revelation that really started placing Rooney's name in transfer rumors for the current window.

Arsenal and Chelsea have both been mentioned as rival sides who will have interest for the star striker if his days at Old Trafford are numbered. As noted by James Boylan of Metro, both the Gunners and the Blues are reportedly prepared to come close to United's valuation of £25 million in a potential transfer.

Per Boylan, Paris Saint-Germain remains in the hunt for Rooney if United decide to sell.

Wednesday marked a pivotal day in the Rooney-United saga, as the star striker was scheduled to make his way to United's training ground for a medical test and a much-anticipated meeting with Moyes about his future at Old Trafford.

According to a report from Sky Sports, that meeting has yet to take place.

Rooney completed his medical tests and stayed just over three hours at United's training grounds on Wednesday, per the Sky Sports report.

However, that three-hour visit did not include a face-to-face visit with Moyes, who was in the third day of his new job as Rooney made his way to the grounds for the first time since the 2012-13 EPL season ended.

News broke later in the day that Rooney will now have to make a formal transfer request if he's indeed destined for football life outside of Old Trafford in the next phase of his career.

According to Jackson's Wednesday night report for the Guardian, the Red Devils will play hardball with the rumors surrounding Rooney's "unhappiness" with the club and force him to make his intentions of playing elsewhere public before a deal will be made.

Jackson maintains that details are still murky about whether a Rooney-Moyes meeting took place, but he also asserts that the new manager is in no rush to sell the striker.

That hasn't stopped others from peeking into the discomfort surrounding the subject.

Chelsea goalkeeper Petr Cech and Arsenal's Jack Wilshere were both quoted on Rooney in recent days (per the Sky Sports report above), and each are quick to project Rooney's immense talent as worthy of a spot on their respective team.

Rooney has been in and out of transfer rumors since the 2012-13 EPL season ended. It was no secret that tensions with Ferguson were strained, as Rooney was not a first-choice player for the former boss down the stretch in EPL action.

But the striker managed 12 goals and 10 assists in 22 matches for the Red Devils last season, proving that he's still a capable player worthy of competing at the highest level of English football moving forward.

The prevailing question remains: Will that football be played for United?

Only time—and the reported sit-down with Moyes—will shed enough light on the situation to interpret whether or not Rooney has played his last home match at Old Trafford.
